Question

question 3 of 10
the blue segment below is a diameter of o. what is the length of the radius of the circle?
a. 3.7 units
b. 14.8 units
c. 11.1 units
d. 7.4 units

Explanation:

Step1: Recall the relationship between radius and diameter

The formula for the radius \(r\) of a circle in terms of its diameter \(d\) is \(r=\frac{d}{2}\).

Step2: Substitute the given diameter value

Given that the diameter \(d = 7.4\) units. Substituting into the formula: \(r=\frac{7.4}{2}\).

Step3: Calculate the radius

\(\frac{7.4}{2}=3.7\) units.

Answer:

A. 3.7 units
